Havlngthus fully described my invention, what I claim is:

1. In a spring structure, the combination of a coiled spring formed of wire with enlargements at its ends, and cushioning means for said spring comprising a fibrous body of cylindrical external form with said wire extending axially thereof throughout its length with said enlargements embedded in the end portions of said body, and a casing of thinflexible material enclosing and engaging the surface of said body throughout its length and-closed at its ends to confine the ends of said body therein with said enlargements embedded "within said-end portions of said body, to

'secure'saidcushioning means'to 'said wire;

2. In a spring structure, the combination of a spring formed of a coil of wire with a loop at each end, a tubular member sleeved "upon said wire and covering the same between'said loops, and

eushioning means for said spring comprising a body formed-ofseparate fibres loosely compact-ed place uponsaid wire.

.casing maintaining the body in cylindrical form and together with said loops securing said body in 3. In a spring structure, the combination of a plurality of vertically disposed coiled springs formed of'wire, a tubular member sleeved upon said wire forming each spring and having an in- V ternal diameter substantially equal to the diameter'of said wire and extending throughout the lengthof said spring, and cushioning means for each spring comprising a loose fibrous body of cylindricalform sleeved upon said tubular member throughout the lengththereof, and a casing of thin flexible material enclosing said body in contact with the surface thereof throughout its length, said casing being closed at its ends overv the'ends of said body to confine the material of V the body therein, said tubular member onsaid wire being formed of a material adapted to adhere to saidwire and to which the fibrous material of ,the bodyis adapted to adhereto prevent said fibrous material from moving longitudinally of said wire and bunching up within saidlcasi'n'g.
